Heating and cooling curve of water essay sample gelatine is a clear, colorless, brittle (when dry), flavourless solid substance, derived from the collagen inside the skin and bones of animals substances containing gelatine or functioning in a similar way are called gelatinous gelatine is an irreversibly hydrolysed form of collagen. This report details the scientific method used to investigate the effects of water temperature on the rate at which the water will evaporate project design plan: problem statement - the purpose of this experiment was to compare the effect of temperature on the evaporation rate of water the vision was to establish three containers of water. Ten main uses of water (essay sample) september 13, 2017 by admin essay samples, free essay samples producing a cooling effect movements of water inside our bodies allow the transfer of vital antibodies and blood components which regulate our osmotic balance and boosts our immune system outside the human body, water has other uses too.
The volume of water we used the temperature of the water the length of the experiment the time we measure the each of the readings the same liquid we’ll conduct the test with eg water the material we perform the experiment on eg wood we will use a standard glass beaker and fill it up to 200ml. 2 boil water in the kettle and then pour the water into the beaker, and fill up to 200ml insert thermometer 3 when the temperature falls to about 82c securely fit the extra material over the top but leave room for the thermometer to stay in (make sure you can clearly still read off the thermometer) 4.
For this investigation, the effect of the temperature of water upon the rate of cooling will be investigated the temperature-drop over 5 minutes (600 seconds) will be measured for 200ml of water at different start temperatures. Water is often considered to be one of the most important resources our planet has, and rightly so although people don’t need to be surrounded by water all the time, we shouldn’t forget that a human being can survive without food for about several weeks, but without water he would die in the matter of days. I predict that as soon as i pour the boiling water into the beaker the water will begin to cool down, quiet fast at first but then the rate of cooling will start to slow down and eventually stop cooling as the temperature of the water levels off with the temperature of the surroundings ie the room temperature.
Water has a high specific heat capacity this makes it a very useful material for storing and carrying heat energy its heat capacity is 4200 joules per kilogram per i we will write a custom essay sample on rate of cooling specifically for you for only $1638 $139 leave your email and we will send you an example after 24 hours 23:59:59. Cooling rate of water essay cooling rate of water essay 1264 words aug 13th, 2013 6 pages show more this law, mostly referred to as newton’s law of cooling, which states that the rate of cooling of a body is directly proportional to the difference of temperature of the body and the surrounding it implies that the body will loose heat. Essay/paper sample on a given topic essay on importance of water in our life importance of water in our life water is the most important substance in the world, a necessity utilized by living things for survival but also necessary for several processes.
Factors affecting the rate of cooling - sample essay introduction: the experiment will take place with three conical flasks with the same amount of water in each flask the three flasks will be different colours, which are black, silver and a clear glass.
Controlled variables - the controlled variables were the air humidity, the air speed, the room temperature, the type of water (tap), the amount of water, the location where the water was placed, the size of the containers used, the number of tests conducted, the type of the containers used, and the length of time the water had to evaporate. To give one example, in kuwait the consumption rate of water increased rapidly after the discovery of oil in 1930s this discovery naturally brought a great deal of wealth to the country and people began to buy consumer goods that they had not had before such as washing machines, refrigerators and dish washers and to install such things as showers and bathrooms. Fresh water cooling system introduction although there is an abundance of free sea water available, marine diesel engines do not use it directly to keep the hottest parts of the engine cool this is because of the corrosion which would be caused in the cooling water spaces, and the salts which would be deposited on the cooling surfaces interfering with the heat flow.
A graph of the temperature of the system versus the amount of heat added (or temp vs time if the heat is added at a constant rate) is called a heating curve you made a heating curve for water as it melted, then heated then vaporized in lad 5 and a cooling curve for paradichlorobenzene as it goes through a cooling-freezing-cooling process in lad 6.
The problem for this experiment is to investigate the rate of cooling in three different types of cups the cups a polystyrene cup, a paper cup and a plastic cup water has a high specific heat capacity this makes it a very useful material for storing and carrying heat energy we will write a custom essay sample on rate of cooling.
